Try to guess the master's pattern. Press a colored circle to change its color. When you have a line ready to compare to the master's, press 'try'. A black dot shows you that one of the pegs is the right color and in the right place, a white dot shows you that one of the pegs is the right color but in the wrong place. Press 'new' to start a new game, or 'end' to give up and see the master's pattern. (This version uses a feature that doesn't work online. Download it to play.)
